What this skill tells the agent

Android Emulator

Require the agent-device CLI to be installed separately before driving an emulator:

npm install -g agent-device@latest

Treat installation and upgrades as user-owned setup steps. Do not run that command autonomously or substitute a mutable npx -y agent-device@latest invocation.

For a normal app-driving task, start immediately. Do not probe first with --help, --version, devices, appstate, snapshot, or screenshot. Target Android explicitly when opening an app or package id:

agent-device open <app-or-package-id> --platform android --foreground

Follow the initial interactive snapshot and corrective error hints. If the shell reports that agent-device is unavailable, stop and ask the user to install it or expose their existing installation on PATH.

Only when the task is specialized or a command shape is unclear, read the relevant version-matched help topic:

agent-device help validate        # engineering validation and build freshness
agent-device help debugging       # screenshots, logs, traces, video, and failures
agent-device help react-native    # React Native and Expo runtime guidance
agent-device help react-devtools  # component tree, props/state/hooks, and renders
agent-device help scripting       # durable replay and CI workflows
